Abstract
Mayhew and Royle (2008) showed that there are 564 excluded minors for the class of GF(5)-representable matroids having at most 9 elements. We enumerate the excluded minors for GF(5)-representable matroids having 10 elements: there are precisely 2128 such excluded minors. In the process we find, for each , the excluded minors for the class of -representable matroids having at most 10 elements, and the excluded minors for the class of -representable matroids having at most 13 elements.
